Hawaii bowhunting blog
Rancid Crabtree:
With the bitter cold, I went to the local archery shop to shoot indoors today so I could film slow motion footage of these 691 grain arrows with lighted nocks so I could evaluate arrow flight. Here is the footage at 30 and 40 yards.

Rancid Crabtree:
Shooting again today at 45 yards with a different camera angle. The camera is just off to the left of the bow to capture arrow flex. This camera position makes it appear the arrows are flying tail right (they are not) Its just the camera angle so the archer's paradox can be viewed.

Rancid Crabtree:
The back ends of the arrows are all set
So it was time to focus on sharpening the front ends.
Here is a video of the process used to get them hunt ready.

Here is how the broadheads are made.

Rancid Crabtree:
My bow has to travel about 4,000 thousands miles on trucks and planes to get to Hawaii and the current padding in the case sorely lacking for the rigors of such a trip.
A little foam and double sided tape later.
The broadheads also need safe passage so a rubber padded box is in order.
The quiver is set.
The knife is a whole other story. The L39 knife has a good story to tell but that is for another time. I used a knife sharpening guide Im developing to put an edge on it.
Im still rethinking the location and mounting of the Ultimate predator camera on the bow. I think it can be improved upon.
Rancid Crabtree:
I really like the Ultimate Predator Adventure cam for all the features (far better than Go-Pro in my opinion due to things like the ability to zoom, no fish eye , better low light filming) and last year I designed a bow mount and made one on my 3D printer. The 3D printed mount was sound but the supplied housing for the cam allowed too much swing and flex upon release of an arrow. While capturing slow motion footage of the new arrow rest, it was easy to see just how much the camera moved upon release and why the footage I was getting was too blurry to be a value in regards to arrow impacts.
My first printed mount also stuck out to far to the side of the bow so when laying the bow on its side, the camera took all the load. The plan is to design and make a better mount that eliminates the supplied housing and to move the cam from below the sight bar to above the sight bar with a single piece housing bolted right to the sight bracket.
Looking forward to seeing if this mount will improve stability upon arrow release.
